The ROUND function in Oracle SQL is one of the most common mathematical functions. It is used to round a number to a specified number of decimal places. You can use it to round to the nearest whole number, to…
The REMAINDER function in Oracle SQL, like the MOD function, calculates the remainder of a division. However, it uses a different internal formula, which can lead to different results, especially with negative numbers or fractions. While MOD uses the FLOOR…
The POWER function in Oracle SQL is a straightforward mathematical function that raises one number to the power of another number. This is the standard function to use when you need to perform exponentiation, such as squaring a number, cubing…
The NANVL function in Oracle SQL is a specialized function used to handle NaN (Not a Number) values. NaN is a special marker used in floating-point arithmetic (specifically BINARY_FLOAT and BINARY_DOUBLE data types) to represent undefined or unrepresentable results, like…
The MOD function in Oracle SQL is a mathematical function that returns the remainder of one number divided by another. It's also known as the "modulus" function. This function is extremely useful for tasks like determining if a number is…
The LOG function in Oracle SQL is a mathematical function that returns the logarithm of a number to a specific base. While the LN function is always base e, the LOG function lets you choose any base you want, such…
The LN function in Oracle SQL is a mathematical function that returns the natural logarithm of a number. The natural logarithm is the logarithm to the base e, where e is a mathematical constant approximately equal to 2.71828183. This function…
The FLOOR function in Oracle SQL is a mathematical function that returns the largest integer equal to or less than a given number. In simple terms, it always rounds a number down to the nearest whole number. This is the…
The EXP function in Oracle SQL is a mathematical function that returns the value of the constant e (approximately 2.71828183) raised to the power of a given number. This is the inverse of the LN (Natural Logarithm) function and is…
The COSH function in Oracle SQL is a mathematical function that returns the hyperbolic cosine of a given number. This is a technical function used in engineering, physics, and complex mathematics, rather than in typical business reporting. What is the…
The COS function in Oracle SQL is a trigonometric function that returns the cosine of a given angle. It's important to remember that this function, like all trigonometric functions in Oracle, expects the input angle to be in radians, not…
The CEIL function in Oracle SQL is a mathematical function that "rounds up" a number to the smallest integer that is greater than or equal to that number. The name CEIL comes from "ceiling," which is a helpful way to…
The BITAND function in Oracle SQL is a bitwise function. It compares two numbers (or numeric columns) on a bit-by-bit basis and returns a new number as the result of a bitwise AND operation. This function is most commonly used…
The ATAN2 function in Oracle SQL is a powerful trigonometric function. It's the "2-argument" version of the arc tangent. While ATAN(n) calculates the arc tangent of a single number (a ratio), ATAN2(n1, n2) calculates the arc tangent of n1 /…
The ATAN function in Oracle SQL is a trigonometric function that stands for Arc Tangent. It is the opposite of the TAN (Tangent) function. While TAN takes an angle and gives you a ratio, ATAN takes a ratio (which can…
The ASIN function in Oracle SQL is a trigonometric function that stands for Arc Sine. It is the opposite of the SIN (Sine) function. While SIN takes an angle and gives you a ratio, ASIN takes a ratio and gives…
The ACOS function in Oracle SQL is a trigonometric function that stands for Arc Cosine. It does the opposite of the COS (Cosine) function. While COS takes an angle and gives you a ratio, ACOS takes a ratio and gives…
The ABS function in Oracle SQL is a straightforward mathematical function. Its one and only job is to return the absolute value of a number. In simple terms, it makes any number non-negative (positive or zero). If the number is…
